摘　　要：首先分析了LTE与非3GPP互通系统架构配置,描述了3GPP互通系统架构中的逻辑单元(包括用户设备、非3GPP可信网络、非3GPP不可信接入网和EPC),给出了非3GPP互通系统架构中的接口与协议,讨论了非3GPP互通系统架构中的漫游问题。It analyzes the 3GPP and non-3GPP inter-working system architecture configuration, describes the additional and updated logical elements in 3GPP inter-working system architecture configuration which consists of user equipment, trusted non-3GPP access networks, un-trusted non-3GPP access networks and EPC. Furthermore, it presents the interfaces and protocols in non-3GPP inter-working system architecture configuration. In conclusion, it discuss the roaming issues on non-3GPP inter-working system architecture configuration.
